Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn’t just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

Fellow Robots is one company bringing social robots to the market. The company’s ＂Oshbot＂ robot is built to assist customers in a store, which can help the customers find items and help guide them to the product’s location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. ＂We have technologies to train social robots to do things not for us, but with us,＂ said Breazeal.

1.How are social robots different from household robots?

A. They can control their emotions.

B. They are more like humans.

C. They do the normal housework.

D. They respond to users more slowly.

2.What can a Jibo robot do according to Paragraph 3?

A. Communicate with you and perform operations.

B. Answer your questions and make requests.

C. Take your family pictures and deliver milk.

D. Obey your orders and remind you to take pills.

3.What can Oshbot work as?

A. A language teacher. B. A tour guide.

C. A shop assistant. D. A private nurse.

4.We can learn from the last paragraph that social robots will _______.

A. train employees B. be our workmates

C. improve technologies D. take the place of workers

5.What does the passage mainly present?

A. A new design idea of household robots.

B. Marketing strategies for social robots.

C. Information on household robots.

D. An introduction to social robots.

Common sense would tell us that physically active children may be more likely to become active and healthy adults.

In the United States, elementary and middle schools are advised to give students two and a half hours of physical activity a week. That is what the Centers for Disease Control and Prevention and the American Heart Association recommend. They say high schools should provide about four hours of physical activity each week.

Yet many schools across the country have reduced their physical education programs. Just this week, a study reported that lifeexpectancy has fallen or is no longer increasing in some parts of the United States. The situation is worst among poor people in the southern states, and especially women. Public health researchers say it is largely the result of increases in fatness, smoking and high blood pressure. They also blame differences in health services around the country.

In 2006, a study found that only four percent of primary schools provided daily physical education all year for all grades. This was true of eight percent of middle schools and two percent of high schools. The study also found that twenty-two percent of all schools did not require students to take any P.E.

Charlene Burgeson , a health expert says one problem for P.E. teachers is that schools are under pressure to put more time into academic subjects. Also, parents may agree that children need exercise in school. Yet many parents today still have bad memories of being chosen last for teams because teachers favored the good athletes in class.

But experts say P.E. classes have changed. They say the goal has moved away from competition and toward personal performance, as a way to build a lifetime of activity. These days, teachers often lead activities like weight training and yoga.

Some parents like the idea of avoiding competitive sports in P.E. class. Yet others surely dislike that idea. In the end, schools may find themselves in a no-win situation.

1.The underlined word “expectancy” in Paragraph 3 probably means “”

A．quality            B．length            C．exception         D．depth

2.According to the passage which of the following may not lead to poor health?

A．Fatness.           B．Smoking           C．High blood pressure. D．Health service

3.What can be inferred after you read this passage?

A．Physical activities are becoming more and more popular in American schools.

B．All the schools provided daily physical education all year for all students.

C．Parents think children need physical education for their bad memories.

D．Students spent less time on physical education for academic pressure.

4.What is the main idea about this passage?

A．P.E. is the most important subject for all students.

B．P.E has changed its goal for some reasons in America.

C．It introduces us the present situation of P.E in American schools and its cause.

D．P.E can help students improve their academic subjects.

Babies born in summer are more likely to become short-sighted in late life, a study has shown.

As many as a quarter of all cases of short-sightedness are caused by too great an exposure to sunlight in the first weeks of life, say eye experts.

They are advising all parents to put sunglasses on their babies during the first weeks.

Scientists had already established that over-exposure to sunlight caused shortsightedness in animals.

Researchers who compared the months in which babies were born with whether they needed glasses later on say the principle also applies to humans.

A study of almost 300,000 young adults-the largest of its kind-showed that those born in June and July had a 25 per cent greater chance of becoming severely short-sighted than those born in December or January.

Research leader Professor Michael Belkin, of Tel Aviv University, said it was because prolonged illumination(光照) causes the eyeball to lengthen-causing short-sightedness.

Hence the more light a newborn is exposed to, the more the eyeball lengthens and the worse the short-sightedness will be.

The mechanism which lengthens the eyeball is associated with levels of melatonin(褪黑激素), a pigment (色素) which protects the skin against harmful rays of the sun.

In young babies not enough melatonin is released as protection, meaning they are more vulnerable to sunburn and changes to eyeball shape.

Sight expert Professor Daniel O’Leary, of Anglia Ruskin University in Cambridge, said “At the moment we don’t know the precise cause of why light exposure affects sight, but the evidence seems to prove that it is one of the reasons for people becoming shortsighted.”

1.Babies born in summer are more likely to be shortsighted ____________.

A. because the summer sun is too strong for babies

B. because babies born in summer have lengthened eyeballs

C. if they are exposed too much sunlight in the first weeks after they are born

D. if parents don’t know a proper way to protect their babies’ eyes

2.Melatonin is a kind of material to ___________.

A. prevent the eyes from becoming near-sighted

B. protect the skin from harmful sun rays

C. make our body strong

D. protect babies’ eyes from summer sun

3.From what Professor Daniel O’Leary says we can conclude that ___________.

A. there is no evidence that shortsightedness is related to exposure to sunlight

B. whether light exposure affects sight still needs to be further proved

C. he believes that light exposure can cause shortsightedness

D. he tries to give the cause of why light exposure affects sight

4.The underlined word “vulnerable” in the passage probably means __________.

A. easy to be harmed　　　 B. resistant

C. protective　　 　　　　　 D. changeable

Now, if you want to be charming, then you’ll need to build self-confidence, but becoming more outgoing is actually pretty easy. To get to a point at which you feel comfortable talking to complete stranger, follow these steps.

Encourage your curiosity about people.1.I wonder what his parents look like. I wonder what her favorite color is. Is he from around here? Is she the girl I saw at the movie theater last week? It will take some conscious effort, but you can’t be outgoing if you don’t care about people.

Smile at others. Make it a goal to smile at one person a day. It can be anybody, and it can be the most subtle(微妙的) of smile. A quick glance paired with a smile---then run away if you want!2.Eventually, you will want to get to a point where you smile instinctively whenever you make first eye contact with someone.
